Butterflies immediately catch our attention with their beautiful wing patterns and colors. They exemplify metamorphosis with the creeping caterpillar transforming into a soaring butterfly. They have also come to be creatures of science, revealing much to biologists about evolution and the ecological processes and historical accidents that have generated the diversity of life on Earth.In Butterflies, Dick Vane-Wright provides a complete introduction to the biology, natural history, and classification of this major group. Using examples from around the world and eye-catching photographs, he explores what it means to be a butterfly, from how the yellow birdwing finds a mate to why the African gaudy commodores produce adults of different colors.

Bee hives. They might look at first glance like seething anarchy, but the bees know exactly what they are doing. With astounding skill, precise expertise and impressive teamwork they carry out their plans. The Honey Factory plunges the reader into the life of a colony of bees and takes them on a tour of their 'factory'. This is a world inhabited by headstrong individuals with clever methods and an amazing set of rules. Why aren't male bees allowed to stay in their colony just as it is getting cosy? What lies behind the sexual excesses of a young queen bee? And how do all the bees in a hive come to collective decisions? The Honey Factory answers these questions and more. Combining the most fascinating discoveries and greatest secrets in bee research, it ultimately shows readers why bees are so precious and why humans and bees cannot survive without each other.

Bees, both commercially managed honey bees and wild bees, play an important role in global food production. In the United States alone, the value of insect pollination to U.S. agricultural production is estimated at $16 billion annually, of which about three-fourths is attributable to honey bees. Worldwide, the contribution of bees and other insects to global crop production for human food is valued at about $190 billion. Given the importance of bees and other types of pollinators to food production, many have expressed concern about whether a pollinator crisis has been occurring in recent decades. Worldwide reports indicate that populations of both managed honey bees and native bees have been declining, with colony losses in some cases described as severe or unusual. In Europe, managed honey bee colony numbers have been declining since the mid-1960s, and individual beekeepers have reported unusual weakening and mortality in colonies, particularly during the period spanning winter through spring. According to the United Nations, many insect pollinator species may be becoming rarer, causing some to question whether this is a sign of an overall global biodiversity decline. This book examines selected U.S. Department of Agriculture (USDA) agencies bee-related monitoring, research and outreach, as well as conservation efforts, and The Environmental Protection Agency's (EPA) efforts to protect bees through its regulation of pesticides.
